MINERS LAMP.

Specification of Letters Patent.

Application filed October 28, 1913.

Patented Mar. it), 1.914.

Serial No. 797.817'.

T0 all whom fit may concern Be it known that l', PAUL GUILM'AN, a citizen of the United States. residing at East St. Louis, in the county ot' St. Clair, State oit' Illinois7 have invented certain new and uselt'ul improvements in Miners7 Lamps; and do hereby declare the following` to be a full, clear, and exact description o'f' vthe invention, such as will enable others skilled in the art to which it appertains to make and use the same.

This invention relates to miners lamps and has for an object to provide means for positively preventing displacement oit the water regulating valve so that the effective operation of the lamp will be at all times assured.

It is well known that in acetylene miners lamps the Water regulating valve when displaced will either let too much water flow into the carbid chamber or else will shut ott the water altogether, which in either ease results in the lamp becoming extinguished. To obviate this difficulty I provide a novel means for mounting` the valve stem so that it is positively housed against accidental displacement, and may be gotten at easily for adjustment by simply removing the filling cap ot the Water receptacle.

vVith the above objects in view the invention consists oit' certain novel details of construction and combination of parts hereinafter fully described and claimed, it being understood that various modifications may be made in the minor details of construction within the scope of the appended claim.

In the accompanying drawing illustrating this invention z-Fiigure 1 is a longitudinal sectional view through a miners acety iene lamp embodying my improvements. Fig. 2 is an enlarged sectional view on the line 2--2 Fig. 1. Fig. 3 is an enlarged frag mentary sectional view showing the valve stem securing means with the cap in place. Fig. 4t is a plan view o the parts shown in Fig. 3 with the cap removed.

Referring now to the drawing in which like characters of reference designate similar parts, the miners lamp, is shown to comprise a carbid receiving `generating chamber' 10 that carries on its top a removable Water tank 11 that is closed by a concaved top 12, there being an attaching hook 13 on one side of the tank and a lamp reflector 111 and burner l5 on the opposite side of the lamp,

the burner being connected by a tube lf3 to the gcnerz'iting chamber. A.. water pipe 1T opens through the bottom o'f the tank and enters the generating chamber where it is provided with outlet orifices '1S from which the water escapes and combines with the carbid to generatie (he acetylene gas. These parts are all of the usual kind.

fn carrying out my invention the concave top 12 of the tank is provided with a central filling opening 19. Prrrjecf'ing up through this opening and o'l smaller diameter than the opening is a cylindrical (.xf'crnally tlufcaded tube 2() that is secured stationary to the tank wall by means o'l" a spider 21. A nut 22 is .fixcdly secured fo thc spider be low the tube by means oit a band 23. The valve stem 24 seals at the lower end in the intake end ot the water outlet pipe 1T and is formed at the upper end with screw threads 25 which engage in the screw threads ot the nut. The valve stem projects up through the tube and is equipped with a butterfly or wing head 2G by means oit which the valve may be advanced or retracted through the nut t0 control the flow ot' water through the outlet pipe. A cap 2T is provided with internal screw threads 28 that engage with external screw threads 29 on the tube 20, the cap also being provided with a base flange 30 that hears upon the marginal edges ot the filling opening in the top o'f the tank. ft is .now evident that the cap 27 positively houses the valve against displacement :from contact with external objects, while by simply removing the cap the valve may be adjusted easily and quickly.

The tank may be filled by pouring the water down through the tube 20 :from whence it escapes through the spider 21, whatever water spilled on the concaved top ot' the tank gravitating into the tank through that. portion o1 the filling opening 19 that surrounds the tube 20. By virtue ett this construction it will be seen that the wa ter supply in the tank may be replenished from time to time without disturbing the position ot the valve, and that further the valve may be removed tor cleaning at any time without disturbing the position oi its mountings.

That is claimed. is z---A- In an acetylene lamp, a tank. there being a filling opening in the tank top, a threaded tube projecting through and ot smaller diameter than said opening, a skeleton memagainst displacement and closing said iiing 10 ber securing said tube t0 the inner wail of opening.

said tank, a nut carried by said member be- In testimony whereof, I aiiX my signalOWand in alinement with said tube, a valve ture, in the presence of tWo Witnesses. having a threaded stem engaged through PAUL GUILMAN said nut and passing through said tube, and

a cap threaded 0n t0 said tube and having a Witnesses:

base flange engaging the marginal edges of L. A. ZIEI-INERT,
